DESULFURIZATION METHOD OF SULFUR-CONTAINING SLAG, MANUFACTURING METHOD OF CIVIL ENGINEERING CONSTRUCTION MATERIAL UTILIZING SULFUR-CONTAINING SLAG AND MANUFACTURING METHOD OF SLAG CONSTRUCTION BODY
PROBLEM TO BE SOLVED: To provide a desulfurization method of sulfur-containing slag that can remove a sulfur component from sulfur-containing slag at a relatively inexpensive price with good efficiency while reducing environmental load and providing industrial practicability.SOLUTION: The desulfurization method of sulfur-containing slag comprises immersing the sulfur-containing slag in an alkali aqueous solution including calcium ions and dissolving a sulfur component of the sulfur-containing slag in the alkali aqueous solution to remove the sulfur component. A civil engineering construction material is manufactured by utilizing the method and furthermore, a slag construction body is manufactured.SELECTED DRAWING: Figure 3
【課題】環境負荷を小さくして、工業的な実用性を兼ね備えながら、比較的安価に効率良く、硫黄含有スラグから硫黄分を除去することができる硫黄含有スラグの脱硫方法を提供する。【解決手段】カルシウムイオンを含んだアルカリ水溶液に硫黄含有スラグを浸漬し、該硫黄含有スラグの硫黄分を前記アルカリ水溶液に溶解させて、硫黄分を除去する硫黄含有スラグの脱硫方法であり、また、この方法を利用して土木建設材を製造し、更には、スラグ施工体を製造する。【選択図】図３
